The Rainbird ESP or the Hunter Pro-C - but I prefer the Rainbird. Ease of explaining to homeowner for one thing. Of course the Rainbird RC controllers would definately be used for older homeowners. Yes they are expensive but last a long time and there are parts to repair them as opposed to burnt circuit boards and the garbage can.
